Don\'t like... for me would be minimum focus distance and telephoto constraints, plus awkwardness of not viewing through the lens (or seeing an exact frame) for tripod/landscape/filter situations.
For me - I\'m happy to work around those, >135mm telephoto was never that interesting to me, I definitely never took a great shot that was closer than 70cm(!) and the filter/framing thing is do-able, just more challenging than the sitting-on-the-sofa-watching-the-TV-screen experience the Sony provided.
If any of those are really important, you might be better off using an alternative body or the M240 with adapters etc.
But the likes would far far outweigh those constraints for me, having come to RF from a manual focus lens adapted on Sony body.
Cost should also be mentioned! It needn\'t be expensive (or a Leica body/lens for that matter) but it certainly can be.
